Bullet Shell Casing For Smooth Bore Hunting Guns

Abstract

Disclosed is a bullet shell casing for smooth bore hunting guns. The shell casing comprises of a casing made of paper with the ends coated in wax. On its surface, the casing has four twisting grooves the length of the casing. The casing enclosing the bullet is made of identical longitudinal halves having a cylindrical outer surface and an inner surface matching with the surface of the bullet or bullets. The casing has inverted cone indentions at each end of the casing. A plastic compression cone is matched with the rear indention of the casing. Compression cone and casing are fitted into a shell that is not crimped at the end of said shell. The bullet shell casing offers improved longitudinal stability, longer range, and effectiveness.

The invention claimed is: 
     
         1 . A bullet shell casing for hunting guns with smooth bores, comprising: a cylindrical bullet casing defined by a bullet enclosed by an casing, said casing being made of paper having identical longitudinal halves having a cylindrical outer surface and an inner surface matching in contour with said side surface of said bullet or bullets. Said casing ends are coated with wax. Said casing having four grooves on said side surface, said grooves 4 mm wide and 2 mm deep are arranged in a cross pattern at the nose of said envelope. Said grooves twist from the nose left to right of said casing to end directly below the start of the next groove. Said nose portion of said casing has a 5 mm conical indention. The rear of said casing has a 5 mm conical indention to which a plastic compression cone is matched. Said compression cone and casing are fitted into a shell that is smooth and not crimped at the end of said shell. 
     
     
         2 . The bullet shell casing according to  claim 1 , wherein said casing being made of paper with identical longitudinal halves having a cylindrical outer surface and an inner surface matching in contour with said side surface of said bullet or bullets. 
     
     
         3 . The bullet shell casing ends are coated with wax. 
     
     
         4 . The bullet shell casing according to  claim 1 , wherein said grooves are made spiral the length of said casing. Said grooves 4 mm wide and 2 mm deep are arranged in a cross pattern at the nose of said casing. Said grooves begin at the nose of said casing in a spiral the length of said casing to end at the rear, directly below the start of the next groove. 
     
     
         5 . The bullet shell casing according to  claim 1 , wherein said casing has inverted 5 mm conical indentions at each end of said casing. 
     
     
         6 . The bullet shell casing according to  claim 1 , wherein a plastic compression cone is butted into the rear conical indention of said casing. 
     
     
         7 . A bullet shell casing for hunting guns with smooth bores. The said shell casing comprises of a casing made of paper having a light weight. On said casing's surface, the casing has four twisting grooves 4 mm wide and 2 mm deep are arranged in a cross pattern at the nose of said casing. Said grooves begin at the nose of said casing in a spiral to end at the rear of said casing, directly below the start of the next groove. The casing enclosing the bullet is made of paper with identical longitudinal halves having a cylindrical outer surface and an inner surface matching with the surface of the bullet or bullets. The said casing is molded to fit two 50. Caliber round ball, or one 50. Caliber conical bullet for a 12 gauge smooth bore shotgun. The said casing has 5 mm inverted cone indentions at each end. A plastic compression cone is matched with the rear indention of said casing. Said casing and compression cone are fitted into a shell that is smooth and not crimped at the end of said shell.
